live555+ffmpeg如何提取关键帧(I帧,P帧,B帧)开发流媒体播放器的时候,特别是在windowsmobile,symbian(S60)平台开发时,很可能遇到需要自己开发播放器的情况。S60平台提供了CVideoPlayUtility接口可以实现流媒体播放器,但由于非开源,所以相对于自己开发播放器,很多操作受到限制。live555主要用于网络流接收,ffmpeg则是对接收到的数据进行编码/解码。I帧,P帧,B帧是视频流中三种分类,其中I帧也就是关键帧是基础帧,P帧一般根据I帧确定,而B帧需要前面两着的信息。举例说:the Input sequence for video encode 阅读全文
